Tho lhreo parts are suitably connected by sorows or the like. The ring .22 i% 'n'oviclod at its periphery with gear loelh 25. so that tho' Whole rotary member may he rogsu'derl as a gear riln-jouriuiled on the supporting :rz-nuo 1.7. The gear tooth 25 are meshed. by a worm 26 on n shuit 27 gournuled in hearings" on the support and driven G; amo -1:12

gears 29 by Wheel crank handle 30. the shaft of which journaied in the support ai- 3l. This gearing enables the rotary meinher Lo he dri en by hand at unil'orni speed. and the latter in turn moves the lorch at approximately iu'iil'orni speed, with such variation as is produced bylhe cam 32-, which variation is not, however, suliicieul to impair the nature of the out.

The cam 32 extends around the axis of the rotary meniloe: 19., and is of such formation as to guide the torch so that its jets tram-cl along the appropriate path for cutting the desired form of slot, or other opening. Olr viously the shape of the cam will be varied according to the nature of the out desired. This cam is stationary and is preferably cured to the inner side of a cover plate or ring 33, which is suitably secured to an outward-projecting l'lll'l ill on the supporting ring 1?. the parts 17 and 33 thus forming an annular casing. The torch or blow-pipe is mounted on a part :35 which movahly connected. to the driver 19 so as to be capable of moving toward and from the axis thereof as the driver rotatcs. it preferably in the form of a slide having ils end portions awarded to reciprocate in guides 36 on the ring 23. The torch passes through the middle of this part. and through an enlarged in disk which is sufliciently 0rd the requisile scope of lateral The part 35, carrythrough miter large to all movement for the torch. ing the torch, isguided by engagement with the cam 32, and to this end it is provided near one end with a roller 38 which travels on the can'u The latter, it will be seen, is in the nature of a track extending around the axis of the rotary carrier or driver so as to guide the torch carrier, so that the torch travels in the proper path. For convenience the cam is formed of two cam rings and the roller 38 travels in the slot between them. The torch is located on the part at a point nearer the axis of rotation than the contact portion 38, so that the path which is described by the torch uuder the guidance of the cam is dillerent both from the outline of the cam and from the circular nu'weuicnt of the driver. Thus, l'he cam illustrated ol' the appr i i'ial'e formation for producing the shape of slot indicated at 39 in Fig. l. In order to adjust the torch exactly to the. desired pah it is mounied in a holder 40. which is adjustable on the part, toward and from the axis of rotation by means of a screw ll. Tho cam pieces 2-52 arc removable and replaceable by detaching the cover plate 313 and substituting: another carrying; a dill'ewiu: Cain. so that by Varying the shape of lhc cam the jei's of the torch can he caused to travel along a dilloreut; path.

The length the slot cut in {he end 0i the web of the rail deeerminenl lay a gage 4-2. in the nalui'c a rod fixed lo the cl am hod 5 front and back portions of the i0 extending lengthwise of ihe rail to he thereof, being provided with laterally projecting head which. contacts with the end of the rail when the clamp has been pUS-IllOHQCl far enough from the rail end. The holder -40 is a .nhular socl-zec provided with a cenlraliz-ing clamp which avoids lab orally displacing the torch in he act of lighlening the holding means. The clamping means is shown as eouwrising a hashing 4-3 having a pluraliiy oi GU UZZllQ SRDHCQQ slots l c t inward from each end, the members the mo sets of slols alternating with each other so as not to weal-fen lhe metal induly. and being preferably extended pas each ciihc at their inner ends. The on s o the, bushing are beveled and engage beveled surfaces e5. formed on one end of ihe body of the holder and on a screw cap or ring 4.6, respectively. T he latter when screwed onto the body of the holder by vii. rue of the beveled surfaces squeezeshotn the bushing; againstthe cylindrical body of the torch 20 When lhe cap is unscrewed the resilience o i he inelal of lhe bushing causes i a. open slighlly, releasing lhe grip on the torch.

The cutting means may he of any suitable or usual construclion and consisls essentially of a device or assei'nhlage for delivering healing and oxygen jets against the work so as to iupidly oxidize. or cut the metal in the Well known manner. heating and cutting jel oi'ificcs are indicated at 47, 48-. respectively. and the conduils for leading as to si'zpply these pass through lho part and carrier 19, and ins'de of the hearing 18 and the cam track 32. the open inclosed by the hearing and cam lra perinilting unobstructed movement of torch and his connections hol'h around the ariis of the rotary member 19 and toward and from the same. The gas cutting means shown a usual form of torch provided with a cylindrical bony held in the holder 40 and inclosing the pipes 29, 50, 51, Whie lead o 'en for the cutting jet, oxygen 1' the hen no 1-. andacel'ylene fortheheating iel'. respecl'ivel 'lhe torch embodies usual prm'isions. n vi. slur-Wu, for causing the oxygen and acel i lcne from pipes 59 and i to nzix he'lore passing; out he heating jet orinee ll. .\i he rear the lurch has conneclicns 532. 53, 4 for allachnient to flexible pipes leadinc luau suitable sources of sup ply.

"l'he torch may he moved forward or backuard. in its holder to position its "lei orifices ax. the proper dislance from the rail web; hirtheru'u:re, lhctorch is removable and replaceable as a Whole.

in operaiion, the device lirs'i clamped ill) weenie:

to the rsii, near the end thereof, and the rotary member is turned until. the tip of the torch is at or beyond the end of the web. The rotary member is tild-Il rotated at even speed so that the torch guided by the coin causes its jets to travel straight inward from the end of the Web, then turn and move s might outward again. The path along which the jets operate can be varied varying the "cm; end in general the com struetion of apparatus can be varied considerably to adopt it for different kinds of work, where it is desired to out along irregular or variously curved lines or lines partly curved and partly straight. A simi lar or modified apparatus could be used with an eutogenous welding torch Where it was desired-to Weld along at line neither straight nor circular.

In Fig. d, which illustretes the reil-sldtting device and its operation in a. semidingrmuuistic manner, the can: surfsces are shown at 353 and the roller at $8. The part 35 is indicated diagrammatically, and the torch carried by it indicated by the circle 20, the positions of the heating and cutting jets being shown at 4:7, 4:8,respectivcly. The outline of the slot cut by the oxygen jet with the assistance of the heating jet or jets is shown at 39. The axis about which the driver 19 rotates is indicated the Wheel 19 and is constrained by the cam 32 to slide in and out on the Wheel always in radial directions. The result is that the jets, or rather the cutting jet travels along the path represented by the outline of the slot. c
